Named after the Dakota Indians of North America, which occupy North and South Dakota, the USNS SIOUX was the sixth POWHATAN - class ocean tug. The Indian tribe after which the SIOUX was named became known as the Sioux from a mispronounciation of an enemy tribe's word meaning "snake."
The USNS SIOUX was equipped with a 10-ton capacity crane and a bollard pull of at least 54 tons. A deck grid was fitted aft which contained 1 inch bolt receptacles spaced 24 inches apart. That allowed for the bolting down of a wide variety of portable equipment. There were two GPH fire pumps supplying three fire monitors with up to 2,200 gallons of foam per minute. A deep module could be embarked to support naval salvage teams.
After more than 40 years of service, SIOUX was deactivated and stricken from the Navy list on September 30, 2021. The ship is presently laid up at Pearl Harbor, Hi., awaiting final disposal.
